5-1. Essential Information
Introduction
Be careful not to hurt yourself when inspecting your vehicle, replacing
a tire, or doing some kind of maintenance such as car washing.
In particular, wear thick work gloves such as cotton gloves when
touching areas that are difficult to see while inspecting or working on
your vehicle. Doing inspections or procedures with your bare hands
could cause injury.
If you are unsure about any procedu re it describes, we strongly urge
you to have a reliable and qualified service shop perform the work,
preferably your Toyota dealer.
Factory-trained Toyota technicians and genuine Toyota parts are best
for your vehicle. Without this expe rtise and the parts that have been
designed and made especially for your Toyota, inadequate, incom-
plete, and insufficient servicing may result in problems. This could
lead to vehicle damage or an accident and injuries.
For expert advice and quality service, consult your Toyota dealer.
To continue warranty eligibility and to protect your investment, it is
your responsibility to pr operly maintain your vehicle according to fac-
tory recommended schedul es outlined in this manual. Keep a copy of
the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while
your vehicle is under warranty, your Toyota dealer will promptly take
care of it.
This evidence may consist of the following: • The Maintenance Log, found within the Warranty and Maintenance Guide, must be completely filled out showing mileage, repair order
number, date for each service, and signed by a qualified automotive
service technician who service vehicles.
• Original copies of repair orders or other receipts that include the mileage and date the vehicle was serviced. Each receipt should be
signed by a qualified automot ive service technician.
• For self maintenance, a statemen t that you completed the mainte-
nance yourself, displaying mileag e and the date the work was per-
formed. Also, receipts for the replac ement parts (fluid, filters, etc.)
indicating the date and mileage mu st accompany this statement.

Maintenance and Care
Claims against the warranty resulting from lack of maintenance, as
opposed to defective materials or authorized Toyota workmanship, will
not be honored.
Any auto repair shop using parts equivalent to your Toyota’s original
equipment may perform maintenance. But we recommend that it
always be done by your Toyota dealer using genuine Toyota parts.
Selecting “Maintenance Monitor” enables the system to notify you of
your vehicle’s approaching inspection/servicing period (→P. 414).
The malfunction diagnosis connecto r is designed exclusively for con-
necting the specially designed device to perform on-board diagnosis.
Do not connect any devices other than the specially designed mal-
function diagnosis devices for servic ing. If any device other than the
malfunction diagnosis device is connec ted, it may affect the vehicle’s
electrical devices or lead to damage such as battery depletion.
If you elect to perform maintenance yourself or have your vehicle serviced at
a location other than your Toyota dealer, Toyota requires that all fluids, parts
and materials must meet Toyota standards for durability and performance as
described in this manual.
